Pop ruled on "The Voice" Tuesday night (October 17) as contestants powered through another night of battles with songs by the likes of Katy Perry and Owl City. Celebrity coaches Adam Levine and Cee Lo Green pumped out strong performances by their team members, but it was endearing moments between Blake Shelton and Christina Aguilera with losing hopefuls that lifted the night's usual happenings.

Country Thang

Team Blake's Liz Davis and Nicole Johnson kicked off the show with a good ol' country joust. During rehearsals, Davis encountered some diction issues as a result of her nasal voice while Johnson had some pitch issues. When the battle began, both country beauties took guest mentor Bublé's advice to "destroy" their contenders. The coaches were left confused as to who really won, offering little guidance to Shelton. In the end, he gave the win to the more experienced Davis, pointing out that Johnson lost her breath a few times during the battle, but tracked down a tearful Johnson post-battle to give her a goodbye hug and some last words of support.

Girl Power

It was a battle of future pop princesses between Team Adam's Alessandra Guercio and Kayla Nevarez as they took on current pop diva Katy Perry's "Wide Awake." Nevarez's confidence led to a stronger performance, vocal delivery and the eventual win, with coach Levine feeling pain for Guercio's lack of confidence and need to be perfect. This note hit a special chord with Aguilera, who shared her experience on the Mickey Mouse Club, feeling pressure to fit in when she knew she was different. The comment led to Xtina pushing her button for Guercio in a moment host Carson Daly called the "comeback story" of the season. "No woman should feel not confident on any level," Aguilera told Guercio who was left in shock and utter gratitude.

Good Times?

Pop-rocker Mackenzie Bourg and country singer Emily Earle of Team Cee Lo were both a little out of their comfort zones singing Owl City's "Good Time" in their battle. Bourg was worried about performing without an instrument or prop and Earle felt the pressure of delivering outside of her genre. Both gave a good performance although the chemistry was clearly missing between the young singers. Green saw mixed emotions with Earle onstage, who felt a bit uncomfortable with a male partner. Bourg, on the other hand, brought his A-game with Green noticing his potential to do "anything." Bourg won.
